The Use of QBIC Content-Based Image Retrieval System [PDF]
Journal of Library and Information Studies, 2004 The fast increase in digital images has caught increasing attention on the development of image retrieval technologies. Content-based image retrieval (CBIR) has become an important approach in retrieving image data from a large collection.

Info Navigator: A visualization tool for document searching and browsing [PDF]
, 2003 In this paper we investigate the retrieval performance of monophonic and polyphonic queries made on a polyphonic music database. We extend the n-gram approach for full-music indexing of monophonic music data to polyphonic music using both rhythm and ...

Learning Visual Features from Snapshots for Web Search
, 2017 When applying learning to rank algorithms to Web search, a large number of features are usually designed to capture the relevance signals. Most of these features are computed based on the extracted textual elements, link analysis, and user logs. However,

The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1
FEBS Letters, EarlyView.MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Adapting to the Shifting Intent of Search Queries [PDF]
, 2009 Search engines today present results that are often oblivious to abrupt shifts in intent. For example, the query `independence day' usually refers to a US holiday, but the intent of this query abruptly changed during the release of a major film by that ...

FEBS Letters, EarlyView.In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Identification of pattern languages from examples and queries
Information and Computation, 1987 Pattern languages are defined by \textit{D. Angluin} [J. Comput. Syst. Sci. 21, 46-62 (1980; Zbl 0454.68108)] as an abstract model of learning one- dimensional patterns. A pattern is defined to be a string of variables and constants, and its associated language is defined to be all constant strings obtained by substituting constant strings for ...

Context-Free Path Querying by Matrix Multiplication
, 2017 Graph data models are widely used in many areas, for example, bioinformatics, graph databases. In these areas, it is often required to process queries for large graphs. Some of the most common graph queries are navigational queries.
